MACHINE FOR CLEANING INTESTINES.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application filed June 3, 1910. Serial No. 564,845.

To all whom it may concern:

Be it known that I, ERWIN O. FREUND, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements Relating to Machines for Cleaning Intestines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to a machine for cleaning intestines and its object is to pro duce a new and improved machine by which the intestines may be carried away from the co-acting scrapers and drum automatically, and automatically delivered to and hung to suitable receiving devices, thus doing away with the service of an extra helper, usually employed in machines of this character, to pull the cleaned and stripped intestines through the machine.

In the accompanying drawings: Figure 1 is a top or plan view; Fig. 2 is a vertical section on line 22 of Fig. 1; Fig. 3 is a vertical section on line 3-3 of Fig. 1 showing a portion of the supporting bracket in dot-ted lines; Fig. 4 is a side elevation viewed from the left in Fig. 1; and Fig. 5 is an enlarged detail of the hook which engages the intestines and carries them through the machine.

Referring to the drawings,-6 indicates the framework upon which the other parts, hereinafter described, are mounted.

7 indicates a table carried by the framework 8 indicates the main driving shaft of the machine which may be driven from any suitable source of power by driving pulley 9.

10 indicates a belt-shifter adapted to shift the driving-belt, not shown, to idler-pulley 11, or from it to driving pulley 9.

12 indicates a drum, which is formed of two parts, 12 and 12, which is mounted upon shaft 13, journaled in the framework of the machine and driven in any suitable way as by belt 14 passing over pulleys 15- 16 mounted respectively on shafts 8 and 13. Of course, if desired, a sprocket-chain and sprocket-wheels may be employed instead of belts and ordinary pulleys. The drum 12 is divided into two parts separate from one another, as is best shown in Fig. 1, in order to permit the placing between them of a stationary member 17 secured upon table 18 carried by the frame 6. The stationary member 17 is loosely mounted with reference to the shaft 13 so that the shaft may revolve therein. The outer surface of the member 17 is in the arc of a circle corresponding to the periphery of drum 12, and the member, roughly speaking, is in the shape of a segment of a circle concentric with the drum so as to leave a space for the passage of the sprocket-chain, hereinafter described, be tween the two members of the drum 12. The drum rotates in the direction shown by arrow in Fig. 3.

151-20 indicate suit-able scrapers provided with blades 19 and 20. They are mounted respectively upon shafts 2122 which are journaled at one end in the framework of the machine and at the other end in a shield 23 hereinafter described and are driven by suitable connections from the drive-shaft. They revolve in the same direction as the drum 12, but at a very much higher rate of speed.

23 indicates a shield which is suitably placed to protect the operator in placing the intestines in the machine. The shield 23 is secured at its inner end upon suitable supports in the framework, as crossbars 6, above and behind the drum 12 and at its other end stands free from said drum so as to permit the insertion of the intestines over the drum from the sine of the machine. The shield also is provided with braces, as 23, secured to the framework of the machine, as to the crossbars 6*, and serves also to support the outer end of the scrapers. The shaft 13 is preferably mounted in the slide-boxes 2elsee Fig. 4which, by means of a set-screw 25, may be moved in one direction or the other longitudinally of the machine so as to adjust the drum 12 with reference to the scrapers. Except for the fact that the drum is divided into two sections with the stationary member 17 between them, for the purpose hereinafter more fully described, the drum, scrapers and shield operate in the well known manner, which will be hereinafter more fully described in describing the operation of my entire machine and it is believed therefore that no further detailed description of them in this place is necessary.

26 indicates a gear secured on shaft 8. 27 indicates a beveled gear secured on the same shaft.

28 indicates a gear secured on shaft 29 suitably journaled in the framework of the machine. The gear 28 meshes with gear 26.

30 indicates a beveled gear secured to the shaft 29. The beveled gear 27 meshes with beveled gear 31 which is secured to an upright shaft 32 which is suitably journaled as in brackets 3334 mounted on the framework of the machine.

35 indicates a worm on the shaft 32 which meshes with worm-wheel 36 which is secured to shaft 37 suitably journaled in the framework of the machine.

38 indicates a roller on shaft 37 in alinement with table 7.

39 indicates sprocket-wheels which are secured on the shaft 37 in a suitable peripheral groove on roller 38.

40 indicates a beveled gear which meshes with gear 30 and which is secured to vertical shaft 41 suitably j ournaled in the frame of the machine as by brackets 4243.

44 indicates a worm on shaft 41.

45 indicates a worm-wheel secured on shaft 46 which is suitably journaled in the framework of the machine. The wormwheel 45 engages worm 44 on shaft 41.

47 indicates a roller corresponding with roller 38 mounted on shaft 46.

48 indicates sprocket-wheels on the shaft 46, one upon each side of roller 47. The table 7 is cut away, as is best shown in Fig. 3, immediately above roller 47 49 indicates a roller which is carried upon a suitable shaft 50. The shaft 50 is journaled at each end in slide-boxes 51 which are slidingly mounted between guides 52 so as to move up and down therein.

53 indicates expansion springs bearing at their upper ends on cross pieces 54 on guides 52 and at their lower ends upon slideboxes 51 so as to normally tend to yieldingly hold the roller 49 in lower position so as to coperate with roller 38 in the manner hereinafter described.

55 indicates a roller which is carried upon a suitable shaft 56 ournaled at each end in slide-boxes 57 which are slidingly mounted between guides 58.

59 indicates spiral springs which bear at their upper ends upon cross-bars 60 and connecting guides 58 and at their lower ends upon slide-boxes 57 and operate like the springs 53 above described.

61 indicates sprocket-chains which pass over sprocketwheels 3948 and travel across the upper surface of table 7 in contact therewith. The chains 61 are driven by the sprockets 3948 and pass around other sprocket-wheels 626364 and under sprocket 65 all suitably journaled in the framework 6.

66 indicates a sloping plate suitably carried in the framework of the machine as by support 67 with its upper surface immediately below the lower surface of the sprocketchains 61 between sprockets 64 and 65.

68 indicates an engaging member provided with hooked ends 69 and counterbalancing ends 70. The engaging member is pivotally carried on sprocket-chains 61 as is best shown in detailed view in Fig. 5. The counterbalancing ends 70 are heavier than the hooked ends 69 so as to normally throw the hook 69 up in engaging position as is shown in Figs. 3 and 5. As soon as it is carried by the sprocket-chains 61 beyond the sprocketwheel 64 and the lower surface of the counterbalance 70 is adapted to engage the upper surface of plate 66 and table 7 so as to maintain the hook in engaging position, that is to say, in the position shown in Figs. 3 and 5, until after it leaves the surface of the table.

71 indicate sprocket-chains which pass over, and are driven by, sprocket-wheels 72 which are sunk in suitable peripheral grooves in rollers 3847, respectively. The chains 71 are placed one upon each side of the table 7 near the ends of the rollers 38-47. The chains 71 pass over sprocketwheels 747576 all of which are idlers and are suitably journaled in the frame of the machine.

77 indicates cams which are secured upon the outer surface of sprocket-chain 71 so that their centers are in practical alinement with the engaging member 68. The cams 77 are of suflicient height, that is to say they extend above the upper surface of sprocketchains 71, at a suflicient distance, so that their upper surface may be at least as high as the upper surface of hook 69 when it is in engaging position. The function of the cams is to raise successively rollers 5549 as they pass under them carried, by sprocketchains 71, in order to permit the passage thereunder of engaging hooks 69, as hereinafter described, and to allow the rollers again to descend under the action of the springs as soon as the cams are passed beyond them. This lifting of roller 55 is incheated by dotted lines in Fig. 3.

78 indicates projecting plates which extend over sprocket-chains 61 forming a longitudinal slot between them through which the hook 69 extends and on which said hook travels.

79 indicates a curved receiving hook, secured to the framework of the machine, with its forward end curved upward close to the descending portion of sprocket-chain 61 so as to engage the looped intestines as they are carried around by hook 69 and remove them from said hook as hereinafter described.

80 indicates a worm mounted on shaft 81 which is journaled in the framework of the machine a suitable distance above table 7.

The shaft 81 is driven by a belt 82 passing 7 worm 80 and between which and said worm the doubled intestine passes.

The operation of this machine is as follows. The doubled intestine is passed by the attendant in the usual manner between scrapers l920 and drum 12, being passed in from the side of the machine shown in Fig. 4, and the cooperation of the drum and scrapers operate to scrape and clean the intestine in the usual well known manner. The looped end is pulled forward by the attendant over the drum against the backward pull of the rapidly moving knife-blades 19 and 20 until the loop passes beyond the edge of the opening between the two members of the drum and the fixed member 17 in position to be engaged by the hook 79 which, broughtinto engaging position by the belt 66 as above described, engages the intestine. The looped end of the intestine is carried under worm 80 and forward toward rollers t755. Before the hook passes between the said rollers cams 77 operate to lift roller 55 to permit the passage of the hook below them. The roller &7, of course, is driven in the direction indicated by arrows shown in Fig. 3 by the action of the worm 4: 1, the roller 55 being driven by frictional contact with roller 17. The doubled intestine is next carried by the hook between rollers 38t9, the roller 19 being lifted in the same manner by cams 77 to permit the passage of the hook thereunder. The roller 38 is, of course, driven by worm 85 and worm-wl'ieel 36 in the direction indicated by arrows in Fig. 3, the roller 49 being carried around in the direct-ion indicated by arrows by frictional contact with roller 38. The hook passes still farther forward between rollers 38a9 and travels downward until the looped end of the intestine is engaged by the point of the supporting hook 77 and removed from hook 69. The remainder of the intestine is carried forward by the action of the rollers until its free ends pass beyond the rollers 38- 19 and are free to drop, leaving the looped, cleaned and stripped intestine hanging upon the hook 79. In the meanwhilethe rotation of the worm 80 en gages the intestine and operates to carry the free ends of the intestine over toward the center of the machine and toward the inner end of the drum 12 leaving the space free for the placing of a second intestine into the machine. I have shown only one engaging member 68, and one set of cams 77. It is, of course, obvious that several of such engaging hooks and cooperating cams may be used, the number depending upon the size and capacity of the machine.
